High-strength fishtail bolt
Product Description
螺栓，机械零件，配用螺母的圆柱形带螺纹的紧固件。螺栓：由头部和螺杆（带有外螺纹的圆柱体）两部分组成的一类紧固件，需与螺母配合，用于紧固连接两个带有通孔的零件。这种连接形式称螺栓连接。如把螺母从螺栓上旋下，又可以使这两个零件分开，故螺栓连接是属于可拆卸连接。 按连接的受力方式分：分普通的和有铰制孔用的。按头部形状分：有T形的，六角头的，圆头的，方形头的，沉头的等等。其中六角头是常用的。一般沉头用在要求连接的地方。应用非常广泛。 螺栓有很多叫法，每个人的叫法可能都不同，有人叫成螺钉，有人叫成螺栓钉，有人叫成标准件，有人叫成紧固件。虽然有这么多叫法，但意思都是一样的，都是螺栓。螺栓是紧固件的通用说法。螺栓的原理是利用物体的斜面圆形旋转和摩擦力的物理学和数学原理，循序渐进地紧固器物机件的工具。
螺栓在日常生活当中和工业生产制造当中，是少不了的，螺栓也被称为工业之米。可见螺栓的运用之广泛。螺栓的运用范围有：电子产品，机械产品，数码产品，电力设备，机电机械产品。船舶，车辆，水利工程，甚至化学实验上也有用到螺栓。反正是超多地方都有用到螺栓的。特如数码产品上面用到的精密螺栓。DVD，照相机、眼镜、钟表、电子等使用的微型螺栓;电视、电气制品、乐器、家具等之一般螺栓;至于工程、建筑、桥梁则使用大型螺栓、螺帽;交通器具、飞机、电车、汽车等则为大小螺栓并用。螺栓在工业上负有重要任务，只要地球上存在着工业，则螺栓之功能永远重要。
